Container Linux (CoreOS) is an exciting new Linux implementation that is designed for high performance/low overhead environments.
Many Centrify customers are adopting CoreOS and containers as a standard for deploying applications.
When I installed a Container Linux OS in my environment, the first thing I noticed is that the account normally called "root" is called "core". Normally you log in with an SSH key.
It's possible to store this "core" account in the Shared Account Password vault using the following steps:
1) Log in to your Container Linux as "core" using the SSH key.
2) Set the password for the "core" user.
>sudo passwd core
3) Now create a Resource record in Centrify for this CoreOS Instance. Register the IP address and save the record.
Create your CoreOS record in Centrify
Now register the "core" account, enter the password and select 'Manage this password'.
After this, you can check out the "core" account and log in directly to your instance without seeing the password.
